Pterosaour drag

Anyway, the most prominent theory about how flying pterosaurs hunted was that they would swoop down and skim the water for fish. However some recent research suggest that the drag that this behavior would produce exceeded the amount of energy a pterosaur would reasonably be able to generate.

I love this stuff, I would love to be able to see the trolley mechanism in action that they used to study the drag generated by a modern skimming bird and the 6 1/2 foot skull of a pterosaur
